YNR8040-471M是YJYCOIN(益嘉源) 推出的磁胶屏蔽功率电感,属于小功率贴片电感系列。型号中:
该产品采用SMD贴片封装,适配自动化SMT生产,是紧凑电路设计中平衡性能、成本与EMI控制的优选方案。
电感标称值为470uH,精度±20%,实际值范围为376uH~564uH,满足一般小功率储能、滤波场景的需求(无需高精度谐振电路的场合)。
连续工作额定电流为500mA,指环境温度25℃时,电感允许温升(通常≤40℃)范围内的最大连续负载电流。若电流超过此值,线圈铜损(I²R)会导致过热,可能引发电感值漂移或磁芯损坏。
线圈直流电阻为1.26Ω,直接影响铜损:当负载电流为500mA时,铜损约为0.5²×1.26=0.315W,需在PCB设计中预留适当散热空间(如加宽焊盘、增加铜箔面积)。
采用磁胶屏蔽结构,相比非屏蔽电感,可降低80%以上的电磁辐射(EMI),减少对周边敏感电路(如射频模块、传感器)的干扰,适合对EMI要求严格的应用。
SMD封装规格为8×8×4.2mm(长×宽×高),属于小型化贴片电感,可有效节省PCB空间,适配便携设备、IoT节点等紧凑设计。
该电感因小电流、低EMI、紧凑封装的特点,广泛应用于:
YNR8040-471M以高性价比为核心,兼具:
是消费电子、IoT及汽车电子辅助电路中,平衡性能与成本的实用型功率电感方案。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
